Answer:
a-b=10
Step-by-step explanation:
add all the numbers then round
13+ 14+ 22+ 52+ 63+ 77=241
Round to the nearest ten
a =240
first rounding each number to the nearest ten and then add
13+ 14+ 22+ 52+ 63+ 77
10+10+20+50+60+80 =230
b= 230
a-b = 240-230
= 10
Answer:
x < -6
Step-by-step explanation:
X/4 < -1.5
Multiply each side by 4
X/4*4 < -1.5*4
x < -6
For this case we can use the following rule of three:
$ 500 ---------> 100%
$ 400 ---------> x
Clearing x we have:
x = (400/500) * (100) = 80%
Therefore, the percentage of decrease in the rent is:
p = 100-x
p = 100-80
p = 80%
Answer:
a proportion can be used to calculate p is:
p = 100 - ((400/500) * (100))
